Higher Nahm Transform in Noncommutative Geometry

Tsuyoshi Kato  (Kyoto University)

10:00-11:00, April 9, 2018   Science Building A1510




Abstract:

Anti-self-dual (ASD) connections for a compact smooth four manifold arise as critical values for the Yang-Mills action functional. Nahm transform is a nice correspondence between a vector bundle with ASD connections and vector bundle with ASD connections over Picard torus associated to X. In this talk we propose a noncommutative geometric version of the Nahm transform that generalises the Connes-Yang-Mills action functional formulated using Dixmier trace.
